I don't know if global warming is real or not; and if it is real, I don't know if its primary cause it human activity or something else.

I do know that the resemblance between the rhetoric of conservative fundamentalist Christians and that of liberal environmentalists is quite startling. In both cases, you are not only a sinner who should be silenced and cast into the outer darkness if you disagree with them; you are a sinner who should be silenced and cast into the outer darkness if you indicate that you don't think the evidence either way is solid enough for you to form an opinion.

But each group will say that their position is fully logical and the other group's position is ignorant fanaticism.
